A military judge at Guantanamo Bay has ruled a 9/11 defendant incompetent to stand trial after a military medical panel found that the man's abuse in CIA custody years earlier had rendered him psychotic.

Judge Col. Matthew McCall rendered the decision, Guantanamo military commission spokesman Ron Flesvig said Friday.

Ramzi bin al-Shibh was one of five defendants facing trial in the deaths of nearly 3,000 people in the Sept. 11, 2001, attacks by al-Qaida.

A military medical panel last month diagnosed al-Shibh as having post-traumatic stress disorder with secondary psychosis, and linked it to his abuse during his four years in CIA custody.
